Parameters Parameter Specification Product Series Acti 9 iEM3000 Series (Modular Energy Meters) Device Type Single-Phase Energy Meter Commercial Reference A9MEM3155 Measurement Type Single-Phase, 2-wire (Phase + Neutral) Rated Voltage (Un) 230V AC Base Current (Ib) 10 A Maximum Current (Imax) 65 A Accuracy Class (Active Energy) Class 1 per IEC 62053-21 Key Measurements • Active Energy (kWh) - import (consumption) • Voltage (V) • Current (A) • Active Power (kW) • Frequency (Hz) Display Digital LCD display showing energy consumption and real-time parameters. Pulse Output 1 S0-type pulse output (configurable, e.g., 1000 pulses/kWh) for remote data acquisition or connection to building management systems. Communication (Note) The base model (A9MEM3155) typically does not have a built-in communication bus. For communication (Modbus, M-Bus, Wireless, etc.), an optional communication module (e.g., A9XMWM, A9XMBM) must be added. Power Supply Self-powered from the measured voltage line. Mounting DIN-rail mounting (35 mm), 4-module width (≈ 70 mm). Operating Temperature -25°C to +55°C Storage Temperature -40°C to +70°C Standards & Certifications CE, UKCA, RoHS, compliant with IEC 62053-21.
